Borouge HG385MO
A high-flow, nucleated polypropylene homopolymer engineered for high-performance injection molding. Achieve superior productivity and part quality for packaging, consumer goods, and appliances.
The Competitive Edge in Performance
HG385MO delivers a superior balance of processability and final part performance, making it the optimal choice for demanding, high-volume applications.
High Productivity
Achieve significantly shorter cycle times thanks to a high Melt Flow Rate (25 g/10min) and rapid crystallization from Borealis Nucleation Technology (BNT).
Exceptional Stiffness & Stability
With a Flexural Modulus of 1700 MPa and low warpage tendency from Borstar® technology, parts maintain their shape and structural integrity, even in complex designs.
Downgauging Potential
The high stiffness and high flow combination enables significant wall-thickness reduction, saving material costs and supporting sustainability goals.
Superior Aesthetics
A refined additive package delivers a high-gloss finish and excellent antistatic performance, keeping products looking premium and dust-free on the shelf.
Design for Circularity
As a mono-material, HG385MO is fully recyclable in the #5 plastic stream, supporting sustainable product design and a circular economy.
Good Heat Resistance
A Heat Deflection Temperature (HDT) of 108°C makes it suitable for hot-fill applications and dishwasher-safe housewares.
Powered by Proprietary Technology
The distinguished performance of HG385MO is a direct result of the synergy between two advanced Borealis technologies.
Borstar® Process
This key technology creates a polymer with a narrow molecular weight distribution (MWD). This structural uniformity leads to predictable, even shrinkage, delivering the material's hallmark low distortion and low warpage—critical for large, flat articles like lids and trays.
Borealis Nucleation Technology (BNT)
BNT incorporates highly effective nucleating agents that promote rapid, uniform crystallization. This results in faster cycle times as parts stiffen quickly, and a highly crystalline structure that is the source of HG385MO's exceptional stiffness.
